Hi, I need use correctly the function running-total i have this:
amount running-total
Country1 city1 200 200
city2 100 300
city3 50 350
country2 city1 100 100
city2 20 320 ::) (in this case, i should have 120, not 320)
In my instruction running-total:
running-total(([amount]) for ([city]))
How can i get control-rupture for city and country ???
